12KV Vacuum Contactor with Vacuum Circuit Breaker Integrated - Frequent Switching under Higher Breaking Capacity 31.5kA

Powerful: Rated current ranges from 250A up to 1250A, suitable for various loads including motors, resistors, capacitors and transformers etc.
Robust: Features exceptional breaking capacity and can replace VS1 vacuum circuit breakers, with maximum rated short-circuit breaking current of 31.5KA for high-capacity load protection.
Fast: High-speed operation minimizes impact on capacitor switching to extend load lifespan, achieving 30-40ms closing/opening time with contact bounce time less than 1ms.
Compact: Space-saving fully enclosed structure meets three-proof requirements for easy installation and optimized cabinet space.
Durable: Maintenance-free design withstands over 100,000 operations, ideal for frequent switching.
Adaptable: Flexible terminal configurations for diverse environments, supporting parallel cascading for integrated installations.
